Devi Shastri reports UW students describe chaos as COVID-19 raged through residence halls, leading to lockdown:
Students were running to the Walgreens across the street and the nearby Fresh Market, stocking up on food and supplies. They had been told they had just a few hours before they would be isolated in their dorms for two weeks, inciting panic.
“There were people buying gallons of milk, boxes of cereal, tons of food, cases of water, just stocking up for this quarantine,” [student Lauren] Tamborino said.
Teachers started emailing her to say deadlines on homework assignments were being pushed back. Students were told if they left the dorms after the 10 p.m. lockdown, they would not be allowed back in.
And all of this was unfolding on Wednesday, one week to the day after classes started.
UW-Madison officials sent out information about when meals would be delivered and promised medical care, mental health support and strict enforcement of restrictions on gatherings.
“We know you want to be here and we hope this necessary step will help us achieve the goal of remaining on campus all year,” said a message to students in Sellery and Witte halls.
Watching the chaos, Tamborino knew one thing: She did not want to be here.

Kelly Meyerhofer reports UW-Madison orders more sorority and fraternity houses with COVID-19 cases to quarantine:
More than half of sorority and fraternity houses near UW-Madison’s campus are now under quarantine for at least the next two weeks.
Of the roughly 1,500 fraternity and sorority members who live in university-recognized chapter houses, 820 have received quarantine orders from UW-Madison and the city-county health department. This includes the 420 members put under quarantine last week after 38 members recently tested positive.
The Greek life quarantine orders are in addition to the more than 2,200 students quarantined in Witte and Sellery halls and 124 students in the university’s separate quarantine housing. Altogether, there are at least 3,100 students in quarantine, or roughly 10% of the undergraduate student population, though the number is likely higher when accounting for the unreported number of students who live in off-campus, non-Greek housing also in quarantine.
A UW-Madison list of Greek chapters currently in quarantine includes 22 sorority and fraternity houses. The university recognizes 40 chapter houses.
Yvonne Kim reports ‘Steeper and faster than we expected’: UW chancellor addresses campus COVID cases:
“I think none of us expected quite the magnitude of rise that we saw at the very beginning of this week, which really led us to take action,” [Chancellor Rebecca] Blank said. “We knew that there would be some spikes … Students would come; there would be some partying. The amount of that rise was steeper and faster than we expected, and steeper than some of our fellow schools in the Big Ten.”
